Mexican Spotted Owl Habitat Modelling
This labs objective was to demonstrate the use of a geographic information system for basic habitat modeling by creating a composite binary raster model of potential habitat for Mexican Spotted Owls. The study area for this analysis covers the USGS 7.5 minute quadrangles known as Indian Head Pass, Black Steer Canyon, and Warren Canyon in southeastern Utah. The picture on the left focuses on Black Steer Canyon only.
After reclassifying all the four conditions with a value of 1 (suitable) or 0 (unsuitable) I used the Raster Calculator to add all the four inputs layers together. Red is Highly Suitable with all 4 conditions being satisfied and pink is Suitable with 3 conditions being satisfied.
This table has been created with the help of researchers which identified four model variables for modeling the Mexican Spotted Owl Habitat. The table above describes the four main conditions (landcover, slope, concavity/convexity and aspect) that are the most suitable habitat for the Mexican Spotted Owl.
